i would imagine HTC will have sidebar ads all over facebook and youtube. also theyll have those ads marketed directly to you when you are surfing other sites on the web. like sites you would think have nothing to do with this or aviation type things. im pretty sure that FB and YT uses an ad service or platform that ties into most clickable ads. so if you click an ad for flight lessons, youll start seeing aviation ads at sites like earthcam or what ever other sites you surf.
once that happens AH will start popping like war thunder did. i predict that we will get a ton of war thunder players.
for myself, when those new players get here, i plan on teaching as many as i can about how to play the game smart and aggressive. hopefully get some balls back in this game.
I hope what you say is true about the ads, but going by the last 10 years, I would doubt it very much.

They have a presence on both Facebook and Twitter and even hired someone to manage the accounts. The last post on twitter was Sept 18th, and on Facebook they have a half dozen over the last week, but the one before that was in November. Social media is something that you have to build a buzz about.... hashtags and trending. Posting once a month isn't going to bring the AH name in front of anyone.
To generate interest, those two pages should be updated a few times a day easily. Post pictures from the Alpha, they just posted a video profiling the new sound effects, add more. Shorts showing a pass on buffs, maybe a clip from the big bomber stream they had, a GV taking a shot, another where a round land close to the GV, carpet bomb from a ground view. There are over 100 planes and vehicles, start taking some screen shots and post them.
If they still have a person managing the pages have them post stories, plans, anecdotes about what is going on in the game. Quick "live" updates..... "so and so from such and such squad just dropped the troops to capture airfield A22!", "so and so just landed X amount of kills in an F6F! WTG!", V47's NE spawn has a lot of action going on as the bish look to set up camp!" Any of these little "head lines" can be added to both pages in minutes and will draw attention to the game. Heck those of us that already subscribe and are stuck at work would be all over it just to see what was going on. Those adding more comments will generate MORE attention. Heck have an on-going post that comes up at the same time everyday laying out a battle plan.... how many buffs flying at what alt while fighters grab and forge ahead to cap the target and so on. Once the plan is layed out as a "what if" zip the plan and post it for people to drop into the mission planner as a "saved mission" to try out with their squads.
This is the easy stuff. It doesn't cost a ton of money where you need to worry about the return on the investment. They already have the pages up, they already have someone to post, all they need to do is DO IT! More short videos on youtube will be found by those on those "other games" when they look for videos on flying, or tanking. Grab them with the first link, and keep them interested with new, fresh info everyday. Next thing you know they will be signing up just so they are half decent at the game for when AH3 comes out.
